城市地下网络有害气体远程监测预警系统研究

Harmful Gas Remote Monitoring and Pre-warning System in Urban Underground Network

为提高国内市政地下网络系统的自动化水平,基于MSP430F149单片机开发了城市地下网络有害气体远程监测预警系统。系统由上位机和下位机构成。上位机监控软件采用Visual Basic开发,通过建立气体浓度数据库实现对被监测区域有害气体浓度的实时显示和险情预警;下位机为单片机,用于实时采集气体传感器中的数据,上传至上位机,并通过控制蜂鸣器、排气扇进行现场报警和应急处理。上位机与下位机之间采用GPRS通信模块实时交互。

In order to promote the automation level of the urban underground network systems,this paper devises the all-purpose harmful gases remote monitoring and pre-warning system in underground network based on MSP430F149.This system includes the master computer and the slave computer.The monitoring software of the master computer is developed by Basic Visual,which realizes the functions of real-time display and pre-warning of the harmful gases concentration in the region by establishing the gas concentration database.
